Bei der Herstellung elektrischer Anschlüsse und Verbindungen geht man zunehmend von der Löttechnik auf lötfreie Verbindungstechniken über, da diese sich schneller herstellen lassen und zuverlässiger sind. Zwar werden die einzelnen elektrischen und elektronischen Bauelemente noch häufig mit der sie aufnehmenden Leiterplatte oder gedruckten Schaltung ver- lötet, doch die äußeren Anschlüsse der Leiterplatte werden überwiegend lötfrei hergestellt. Ein Beispiel hierfür ist die Einpresstechnik, bei der ein metallischer Kontaktstift, der einen elastisch nachgiebigen Bereich aufweist, in ein metallisiertes oder durchkontaktiertes Loch einer Leiterplatte aufgenommen wird. Nach dem Einpressen des Kontaktstifts in die Leiterplatte ermöglicht die Presskraft des elastischen Bereichs eine einwandfreie mechanische und elektrische Verbindung zwischen Kontaktstift und metallisierter Lochwandung.In the manufacture of electrical connections and connections, the soldering technique is increasingly being relied upon for solderless connection techniques, since these can be produced faster and are more reliable.

An example of this is the press-fit technique in which a metal contact pin having an elastically yielding region is received in a metallized or plated-through hole of a printed circuit board. After pressing the contact pin in the circuit board allows the pressing force of the elastic region a perfect mechanical and electrical connection between the contact pin and metallized hole wall.
